Here’s the whole run-down:
| Batteries | Hi | Crt |
|---|---|---|
| Lipo | 4.2 | 3.3 |
| LipoHV | 4.35 | 3.3 |
| LiIon | 4.1 | 2.8 |
These are the generally accepted values. Some LiIon cells may have a slightly different critical voltage, but all Lipos are the same.
In MissionPlanner Initial parameters (and the spreadsheet)
BATT_CRT_VOLT = (bat critical voltage + 0.2) x no. of cells
BATT_LOW_VOLT = (bat critical voltage + 0.3) x no. of cells
BATT_ARM_VOLT = (no. of cells - 1) * 0.1 + (bat critical voltage + 0.3) x no. of cells
MOT_BAT_VOLT_MAX = bat high voltage x no. of cells
MOT_BAT_VOLT_MIN = bat critical voltage x no. of cells
